Write down the equations for the decomposition reactions when heated: a) aluminum hydroxide; b) copper hydroxide (monovalent) c) chalk hydroxide (divalent) d) iron hydroxide (divalent)

a) 2Al (OH) 3 = Al2O3 + 3H2O

b) Cu (OH) 2 = CuO + H2O

c) The existence of a compound with the formula CuOH is controversial, CuOH can be a hydrated form of copper (I) oxide: Cu2O.xH2O

2CuOH = Cu2O + H2O

d) Fe (OH) 2 = FeO + H2O
